## Description

A Unraid plugin that lights up the identification (locate) LED of a drive bay from the web UI so you pull the right disk. Adds an ID button to every disk on the Dashboard and Main pages. Works with LSI/Avago/Broadcom HBAs: sas3ircu for SAS3 cards (SAS3008, SAS3216, SAS3224 and similar) and sas2ircu for SAS2 cards (SAS2008, SAS2308 and similar). Both utilities are bundled. Settings let you set the LED colour per enclosure, remap slots to LEDs when backplane cables are crossed, and add a location label for each bay.

## Platform availability

Available on 1 of 9 platforms: Unraid.

## Common questions

### Do I need to install Broadcom's sas2ircu or sas3ircu separately?

No. The Unraid plugin package installs both bundled utilities to /usr/local/bin. Nothing is downloaded from third-party sites.

### How do I map the ID buttons if the backplane LED cables are crossed?

Use Slot to LED mapping in Settings > User Utilities > Disk Identificator to choose which LED sits on each bay. Click Test to check the mapping.

### Does the plugin know which LEDs are on after a reboot?

No. The utilities cannot read LED state back, and the plugin's memory of which LEDs it turned on is lost on reboot.

### How do I refresh the drive list after adding a disk?

The controller and drive list is cached for 10 minutes. Click Rescan in the plugin settings to refresh it.

### How does it match a Unraid disk to the physical slot?

It matches the disk to a slot using the SAS address from the HBA utilities. If that fails, it falls back to the serial number and then the WWN.
